B60}, 1/04, 1/64 U.S. Cl. 214-505 4 ClaimsABSTRACT OF THE DISCLOSURE The means for lifting a heavy goods containerfrom the ground on to a lorry comprise a tilting chassis on the lorry, awinch with doubled cable on the chassis, a double pulley on the rear ofthe chassis over which the cable runs, and a pulley block on the end ofthe cable, the block having two side-ways extending pins at its end. Thecontainer has an insert at its front end with hooks to engage the pulleyblock pins. The lorry is hacked to the container, the block is hooked tothe insert, and then operation of the winch draws the container on tothe false chassis which is tilted to receive the container.

The present invention concerns a hooking device adapted to lift a largecontainer from the ground onto a lorry. The practise of lifting andtransporting containers on to lorries is already known.

The present invention concerns a hooking system which is to be providedon the front of the container so that the hoisting cable of the lorrywinch can be removably fixed thereto.

The device according to the present invention is characterised in thatit comprises, on the lorry, a tilting or false chassis with a winch atits forward end, a cable whose two ends are secured on the winch drumand which is engaged at the rear in a hooking member which comprises athroated pulley and a pulley block provided with two opposed transversestubpins; and, on the container, a rigid lower base which carries areinforced insert located in the centre of the lower part of the frontpanel of the container, said insert being provided on each side with tworollers for rolling over the false chassis of the lorry at the moment ofhoisting, and a rigid centre unit formed in its upper part with twohooks between which the hooking member of the cable may be removablyconnected and, in its lower part, by a return guide for the cableprovided with two throated circular bosses, concentric with the rollers,in each of whose throats one of the runs of the cable is passed, toreturn in the direction of the lorry.

It will be understood that such a device makes it possible to provide atthe rear of the cable only one relatively light member, manipulation ofwhich may be readily effected manually by one workman. Manipulation doesnot require the use of a special tool and the operator is able to putthis member conveniently in position in the insert provided in the frontof the container without having to pass under the said container at anytime Reference should now be made to the accompanying drawings in which:

FIG. 1 is a perspective view showing a container resting on the ground,in front of which is a member provided on the end of the lorry cable.

FIG. 8 is a section taken on the line VIII-VIII of FIG. 6.

FIG. 9 is a section taken on the line IX-IX of FIG. 7 showing thepassage of the cable between the return member of the container and theguide roller of the lorry.

The hooking device shown in the drawings is provided in connection witha container 19 which it is proposed to hoist on to a tiltable falsechassis 10 of a lorry 1.

The container 19 is formed in known manner by walls of light sheet metalfixed to a rigid. base. The latter is formed by two main beams 21connected by tie bars 101 uniformly distributed over the entire lengthThe centre of the lower portion of the front panel 102 of the container19 is provided with a rigid insert panel 103 of thick crossbraced sheetmetal. The insert 103 is recessed in the panel 102 and is directlyconnected to the base 21.

In its centre portion the recess 103 comprises two strong vertical metalmembers 104 in the top of each of which a recess 105 is cut, openingobliquely upwardly and forwardly. In this manner two hooks 106 areformed.

Between the plates 104 and the lower portion of the insert a flange 107of a guide system is welded, the system being constituted by a strongmoulded member. The guide system comprises a vertical rib 108 extendingforwardly out of the upper portion of the flange 1.07 the front end ofwhich carries two cylindrical lateral bosses 109. Each of these bosseshas a circular throat 110 formed in the immediate vicinity of the rib108. To save weight, it is an advantage to make the bosses 109 hollowand to provide the centre thereof with an opening 111 which is continued through the rib 108.

Secured to each side of the insert and in the lower portion thereof isan axle 112 of a roller 113, the two rollers 113 and the bosses 109being co-axially disposed. The rollers 113 and the bosses 109 are theonly members of the insert 103 which extend forwardly beyond thevertical plane defined by the panel 102 of the container 19. The rollers113 are provided to run on longitudinal rails (not shown) provided onthe sides of the false chassis 10 of the lorry 1.

On the lorry 1, the device according to the invention comprises ahooking member 114 provided on the rear end of a cable 15. This cable 15is doubled and its two runs are secured by their respective ends on awinch drum located at the front of the false chassis 10. The member 114comprises a metal pulley block 115 between the two side plates of whicha throated pulley 128 can freely rotate (FIG. 6). The axle 117 of thispulley is fixed to the side plates of the block 115. In its upperportion the block comprises two stubpins 116116, located transversely tothe block. The pins are engageable in the recesses 105 of the hooks 106,whilst the block 115 is disposed'between the two plates 104 of theinsert 103. In its lower portion, the block 115 receives two guideplates 129 which are disposed between its two sides, where they aresecured by bolts 118. It will be seen, more particularly in FIGS. 6 and7, that the cable 15 cannot be disconnected from the member 114 after ithas been mounted thereon, that is to say, when it passes round thereturn pulley 128, whilst its two runs are disposed between the twoopposing plates 129. To complete the assembly, the rear of the falsechassis 10 of the lorry 1 is provided with a centre roller 119 whichserves as a guide for the system 107-108409 at the moment when the front.of the container 19 engages the lorry (FIGS. 7, 9). The two runs of thecable 15 then rest in the throats 110 of the bosses 109, and they areprevented from being crushed by the provision of two opposing throats onthe roller 119. Contact between the roller and the guide assembly107-108-109 is established, along a centre line 121 of the roller 119which bears on the rib 108, and along two inclined lateral lines 122provided on the opposing taper surfaces of the roller 119 and the bosses109. The lines 122 could also be parallel to the axis of the roller.

The operation of the device is as follows:

The container 19 is initially laid on the ground, as shown in FIG. 1. Tohoist it onto the lorry, the lorry is backed in the direction of thefront panel 102. By slackening the cable 15, it is possible to extendthe member 114 from the lorry, which the operator brings close to theinert 103, as shown in FIG. 1. Engagement is efiected by placing the twostubpins 116 in the recesses 105 of the books 106 (FIG. 6), then byplacing the two runs of the cable 15 into the respective throats 110 ofthe bosses 109. The runs of the cable 15 also enter the throats 120 ofthe roller 119 provided on the rear of the lorry 1. The unit is thenready for hoisting (FIG. 2).

The operator starts the winch (not shown) provided on the front of thefalse chassis 10 and draws the cable in the direction of the arrow 123-(FIG. 3). During all these operations, the bosses 109 hold the runs ofthe cable 15.

When the front of the container 19* reaches the rear of the lorry,contact is effected between the rollers 119 and the guides 108-109. Therollers 113 begin to run over the longitudinal rails provided on thesides of the chassis 10 until the container 19 is completely hoisted onto the lorry. Thereafter the container may be clamped or locked inposition if required. Unloading is elfected in a reverse manner to thatdescribed above.

It should be understood that the above description is given only by Wayof example and does not limit the scope of the invention. In particularthe scope of the in- 4 vention would also include modifications of theform or arrangement of the metal ribs 124, 125, 126 or 127 (FIG. 4)provided to reinforce the insert 103.
